AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Wibu-Systems CodeMeter Runtime versions before 4.40 crash via crafted packets on TCP port 22350, enabling denial of service.
Vulnerability
Wibu-Systems CodeMeter Runtime versions 4.30c, 4.10b, and possibly other versions before 4.40 contain a vulnerability in handling TCP packets on port 22350. Sending a specially crafted packet to this port causes the CodeMeter.exe process to crash [1][3].
Exploitation
An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted packet to TCP port 22350 of a system running an affected version of CodeMeter Runtime. No authentication or user interaction is required [1].
Impact
Successful exploitation results in a denial of service (DoS) condition, as the CodeMeter.exe process crashes, disrupting the application's availability [1]. There is no impact on confidentiality or integrity.
Mitigation
Upgrade to CodeMeter Runtime version 4.40 or later, which contains the fix [3][4]. As an interim workaround, restrict network access to TCP port 22350 to trusted hosts only [1].
